End of politics...

These tools control a plate holder, LCD panel, and laser, to make multiplex
holograms.  See http://www.bobdbob.com/~tjohnson/multiplex/ for some additional
details, including what the original hardware looks like.

This was written under FreeBSD, and uses a FreeBSD-specific interface to
the printer port (/dev/ppi0, and a heap of ioctls).  If you're running it under
something else, the routines at the top of multiplex.c are get/set style
functions for the three registers, and should be trivial to replace.

(If you do, please send me your changes... I'm at tjohnson@bobdbob.com)

To use:  

This assumes that the LCD panel is on whatever X server is in $DISPLAY, and
that all the keys have been taken care of.  The images will be put on the root
window with xv.

The script file makehologram does all the real work.  Exposure time and settling
time is at the top.  Theres not a lot to it.  I'll attempt to expand this
as I figure out which details are important.
